Inverter; Rated Power: 55kW; 3x380-480V; Rated Current: 110A; IP00

This compact frequency inverter achieves an exceptional level of performance through a variety of advanced technologies and is ideal for hoist drives or for controlling powerful machines with regenerative torques, such as applications with vertical and horizontal movements in general, conveyors, centrifugal separators, testing machines, winding machines, etc. The integrated regenerative capability allows smaller drive systems and ensures a simplified and space-saving control cabinet design. Compared to conventional drive systems, the FR-A741 with its integrated energy recovery offers potential energy savings here. Thanks to the integrated mains choke and the omission of the external braking unit, there is also no need for additional wiring. This means that compared to the use of an external regenerative unit, the cabling on the mains side is reduced by up to 60 % and the space required for installation is reduced by up to 40 %, depending on the power class. Cable lengths and space requirements in the control cabinet are thus significantly reduced. In lifting applications, it is in its element With the frequency inverters of the FR-A741 series, an innovative and intelligent drive is available that can be easily integrated into complex applications. However, the FR-A 741 is particularly suitable for tasks with cyclical acceleration and deceleration processes, as well as applications where a braking resistor is still used today. Special crane programme functions, such as the sequence for controlling an external brake, load-dependent speed switching and four independent torque limits for all four quadrants, enable simple integration into lifting applications.
